The cheapest GPU that runs Qwen 2.5 VL locally (min 6 GB VRAM) is the Intel Arc B570 (10 GB).
Install Ollama then run: ollama run qwen2.5vl:7b
Minimum VRAM: 6 GB. For best results use Q4_K_M quantization.
Qwen 2.5 VL needs about 6 GB VRAM at Q4_K_M quantization for its smallest variant. Variants: Qwen 2.5 VL 7B Instruct (6 GB, Q4_K_M); Qwen 2.5 VL 72B Instruct (45 GB, Q4_K_M). On Apple Silicon, unified memory counts toward this requirement.
Yes — Qwen 2.5 VL runs on an RTX 4090 (24 GB) and other 24 GB cards such as the RTX 3090. Smaller variants also fit comfortably on 8–16 GB GPUs at Q4_K_M.
Q4_K_M is the best balance of quality and VRAM for Qwen 2.5 VL in most cases. Choose Q8_0 for near-lossless quality if you have spare VRAM, or smaller quants (Q3/Q2) only when memory is tight.
Install Ollama, then run: ollama run qwen2.5vl:7b. This downloads Qwen 2.5 VL and starts a local, OpenAI-compatible endpoint — no internet connection is needed after the initial download.
